IMPROVEMENT IN LOW-WATER INDICATORS.

The Schedulereferred to itx-these Letters'Patent and making p'art of the same.

ATo all whom, it onu/y concern Be it known that I, Wrnnniu MOORE, of Kokomo, in the county of Howard, and State o f Indiana, have invented a new and useful Improvement in Automatic Steam-Boiler Feeders; and'I do hereby'declare that the following is a full, clear, and exact description thereof, which will enable others skilled in' the art to which it appertains to make and use the same, reference being had to the accompanying plates of drawings, which make a part of this specification.

Like. letters in each of the figures denote corresponding parts.

Figure l is a side elevation; Y

Figure 2 is a longitudinal section; and

. Figure 3, a cross-section.

This is specially intended to be an improvement on the patent granted to me, June 5, 1866, and numbered 55,338. In this I claim to have less friction, a sure indication 'to the eye. of the amount of water in vthe boiler, and it is more easily applied to steam-boilers already in use; all Which/will readily "appear by reference to the drawings. Y I attach a steam-chambenby means of a pipe, to thetop of aboiler vof any ordinary-construction, or on the top of any 'auxiliary chamber attached thereto, by means of steam and Water-pipes. Said chamber to be so constructed as to admit of a lever to vibrate up and down inside of it. One end of said lever to be connected by a rod passing through the pipe, connecting said chamber to theboiler. 0n the lower end of said rod is attached the float.` The other or upper end of said rod to connect ata right angle with a shaft passing out of said chamber through a stuiing-box, asseen at M, iig. 3. Said shaft is then connected, by rod W,

fig. 1, to the arrangement, as in my other ypatent referred to, for supplying water'to the boiler.

In iig. lis shown an indeX-handand scale to indi-x cate the rising and falling of the water in the boiler.

At fig. 2 is shown the rod in ,two positions, inside the chamber, as operated bythe float.

At iig. 3 is shown an arm, F, with a coiled spring on it, pressing against an alarm-lever, which causes an alarm by the-Whistle S when the 'water gets so low as to disengage the alarm-lever frombehind said indexhand.

O, in gs. l and 3, is simply albalance to facilitate the operations ofthe iioat.

I do not claim the use of floats, worked automatically, as they have long been in use; but

What I do claim,'and desire to secure' by Letters Patent, is l The combination and arrangement of the chamber A, index-lever, and scale, with the water-regulator, all for the purposes and substantially as herein described and set forth.

In testimony whereof, 'I have hereunto subscribed jmyname in the presence of subscribing witnesses.
